In 2003 the TV show Dawson's Creek came to an end after a successful six year run. Out of the four most notable actors involved in the show – James Van de Beek, Katie Holmes, Michelle Williams and Joshua Jackson – no one could have predicted that out of them all that not only would Williams go on to have the most consistent career in film, but also become one of the most talented actresses of her generation. That must really hurt Katie Holmes.

It's also refreshing to see that she doesn't feel the need to appear in blockbuster after blockbuster, choosing instead to immerse her impressive talents into far more indie-spirited and character-driven pieces such as this.

To all concerned, including Margot (Williams) and Lou (Seth Rogen), this young married couple of five years is happily in love.

Margot writes copy for leaflets to tourist attractions, while Lou is putting together his first recipe book on all things chicken.

Their relationship together appears to be a comfortable one, built on silly voices and childish behaviour.

And then Margot meets Daniel (Luke Kirby); she finds him annoying at first, but then an obvious attraction develops. Meeting this new man forces Margot to evaluate the relationship she's in as well as the possibly damaging affect Daniel will have upon it.

Don't judge me, there's nothing wrong with a liquid diet.

This film marks only the third directorial feature for actress/writer Sarah Polley and it shows a lot of promise. Polley, probably best known for starring in Zack Snyder's 2004 Dawn of the Dead remake, has made a film that although visually warm, contains a lot of curious ambiguity within its leading character in Margot.

Much of this is down to the brilliance shown by Williams in her portrayal of someone who transforms awkwardly into womanhood before our eyes. Her journey however, is a difficult one, not just for her but for the audience watching. She's not the type of character whose actions can easily be understood; her boyfriend Lou seems completely devoted to her and offers no real indication that he could be insufferable in some way. This only reinforces the complexity of the piece; Williams gives a deceptively layered performance that makes it difficult to really like her character, but at the same time make it almost impossible to take your eyes off her.

Kirby, who plays the 'other guy' in the scenario, plays the low-key lothario with aplomb; slowly but surely he brings enough to his character to reveal reasons for Margot's attraction to him.

One of the biggest surprises here though is Rogen; he taps into a genuine earthiness in playing Lou, devoid of trademark wisecracks, offering a performance that is equally touching and heartfelt.

Polley impresses in not only clearly bringing out the best in her talented cast, but in also in bringing her vision to the screen. Take This Waltz is not your usual take on romance as it revels in an honesty not to tie things up with a nice red bow and a happily ever after.

It can be a slightly uncomfortable watch, but at the same time strangely compelling. And for showing off an actress at the top of her game, it can't be beaten.
